Cordless headphones rarely have audiophile sound quality because of the data compression technologies used to transmit the music to the headphones, but Sennheiser‘s new headphones resolve this by using a lossless technology to transmit the sound. Eric Palonen gives Todd and Jeffrey more detail.

The Sennheiser RS 220 are cordless audiophile headphones, based on the reference HD 650 headphones. The wireless transmission technology is based on lossless Direct Sequence Spread Spectrum (DSSS) implementation. The charging base has both digital and analogue inputs.

The RS 220s will be available from March for $599. For comparison, the HD 650s are $499.
